IMPROVEMENT IN HAY-GATHERERS AND SHOCKERS.

The Schedule referred to in these Lettere Pat-ent and making part ox :nesame To all whom yit may concern Beit known that I, CLARK M. TERRELL, ofOskaloosa," in the county of Mahaska and State of Iowa,

l have invented certain Improvements in Combined Hay-- Gatherer,Shocker, and ledder.; and I' do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theannexed drawings, making part of this specification, in which- Figure 1is a sideelevation of my improved machine, showing the guiding-wheel,one of the drivingwheels, the gearing for driving the rake cylinder, andthe frame-work.

- Figure 2 is a plan or top view of thevv parts above enumerated, and ofthe rake-cylinder.

Figure 3 is a sectional elevation of the gathering or rake-cylinder. l

Figure 4 is a sectional end elevation of so much of the machine as isnecessary to the devices for raising and lowering the rake-cylinder.

Figure 5 is an elevation of one of the cylinder-heads, showing its innerside, which is constructed with a cam-shaped groove, wherein the ends oftwo rods are 'made to move by the revolution of the rake-cylinder forthe purpose of reti-acting, at the proper point, the rake-teeth.

Corresponding letters refer to in the several figures.

My invention relates to improvements` on a combined hay-gatherer,shocker, and tedder, for which Letters Patent of the United States weregranted to me on the 17th of September, 1867.

Such improvements consist- First, in the combination and arrangement ofthe cylinder-heads, retracting-rods, and rake-teeth.

Second, in the combination with the rake-cylinder of mechanism foradjusting the same vertically.

Third, in constructing the platform upon which the out grass isdelivered by the rake-cylinder with a hinged flap, infront, so that itcan accommodate itself to various positions of such cylinder.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A, in the drawings, lepresents the truck ofthe machine, which is mountedupon two driving-wheels, B and a swiveling guide-wheel, B', in front.

The driving-wheels are placed loosely upon the axle corresponding partsC, having pawls b pivoted on the inner sides of their hubs, which, asthe machine is drawn forward, engage with ratchet-wheels C', fastened onthe axle, thereby turning the same. In backing the pawls will slip overinto and driving a pinion, D', which latter is secured upon theelongated outer end ofthe rake-cylinder shaft. Thus the latter isrevolved in a direction reverse to that in which the driving-wheels movein the forward motion of the machine.

E represents the rake-cylinder, which is pivoted to the axle C by meansof'two arms or bars formed upon the outer faces of its'heads, andextending the proper distance to the rear, the position of the cylinderbeing in front ofthe axle C. v

The cylinder has secured in it, one near each end. disks E, which arecentrally perforated to receive and be secured upon the shaft E2. Thisshaft has its bearings in boxes formed in the hars of thelcylinder-heads, projecting some distance through one of 'them tzireceive the pinion D'. The periphery of the cylinder is provided withtwo longitudinal series of slots opposite each other, through which therake-teeth are projected.

FF represent two rake-heads, extending from end to end of the cylinder,along opposite sides of its wall, and secured in the disks El.

Upon each one are pivoted teeth Fl, having substantially the forms shownin figs. 3 and 5, and corresponding in number and position with theslots in the cylinder, through which, in the revolutions of the same,they are alternately projected by their own gravity, and again retractedby means of two rods F2, which are also pivoted by their arms f to therake-heads.

These two rodsextend through the cylinder, one within the curvature ofeach series of rake-teeth, and project at each end into cam grooves inthe cylinderheads.

G G represent two disks or heads which coverthe ends of therake-cylinder. Bars Gr1 are formed upon them,

running diametricall y across their outer faces, and, ex-

tendingbeyond them to the rear the proper distance, are pivoted to theaxle, for which purpose they have seats formed in them near their outerends, so thatthey can receive such axle and beheld thereto by means ofcaps in the usual manner. Seats can also be formed in these bars in thecenter of the heads to receive the cylinder-shaft, which is retainedtherein by caps se- Y cured to the bars, as shown.

The inner surface of the cylinder-.heads is constructed with aneccentric cam-groove, G2 into which the ends of the rods F2 project. Theposition and formation of these cam-grooves, and' the arrangement of therods F2 therein, is such that in the revolutions of the cylinder, itsheads with the cam-grooves, of co'urse being stationary, one of theserods shall be gradually forced toward the center of the cylinder as therake-teeth upon which it is to operate rise above the ground, entirelyretracting such teeth into the cylinder by the time their outer ends arein a vertical line with the axila-aud thus holding them until they havepassed mit-ting the rake-teeth upon which it operates, and

`which are by this time below the platform, to again project throughtheslots in the cylinder, which they' will do by their gravity alone.

I H represents a rock-shaft placed in bearing on top of the machine,extending entirely across the same. Its ends are cranked in a horizontaldirection, and connected by means of two connecting-rods H to eyeboltsha, which are secured in the bars G1 of the cylinder-herds, serving atthe same time to secure oneend of the caps covering the cylinder-shaft.

The rack-shaft H is provided with ahand-lever h1, secured upon it nearthe drivers seat, by which it can be turned and the rake-cylinder raisedor lowered.

A hook, 71.2, fastened on the frame may. be placed over it when it isdesired to hold the cylinder in an elevated position.

'lhe connecting-rods pass through slots in the side beams of the truck,and they are on this part provided with screw-threads, and nuts H2 puton them, imping- 'fing upon the upper surface of the beams. By changingthe position of these nuts the rake-cylinder can be stationed at anydesired elevation.

I I represent a series of slats or ngei's, which are y secured to across-barof the truck ofthe machine, in front lof the rake-cylinder,overhanging the same, as shown,rtheir office being to prevent the cutgrass which has been elevated by the rakes to roll back'.

K represents the platform upon which the cut grass is delivered by therake-cylinder. Its front end is provided with a hinged flap, K', restingupon the cylinder, and rising and falling with the same. This platformis to he so arranged on the truck that it can be turned up or entirelyremoved when the machine is to be used as a tedder.

The front end of the flap consists in a piece of sheet metal, so that itcan lay close on the cylinder, and thus prevent the hay from becomingchoked at this point.

L represents the shocker platform, which is to be constructedsubstantially as shown in the drawings. It is pivoted at its front endto the truck, and its rear end, i'om which ,the teeth project, is hungby chains l to eyeboltsL', which pass through and are guided in the`side beams 'of the truck, and are actuated by springs L2 in the mannerset forth in my said former Letters Patent. When traveling with themachine from one field to another the shocker platform is detached fromthe eye-bolts L, and turned up tothe position shown in fig. 1, in whichposition it is held by attaining-its chains to hooks La on the sides ofthe truc M M are two metallic bands, which serve to separate the haywhich is being raised by the rake-cylinder from that remaining on theground, and t0 Drevent the hay from clogging the gearing. V

What I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the grooved cylinder-heads G, the pivotedrake-teeth F1, and retracting-rods F, substantially as and for thepurpose set forth.

2. The arrangement of the rake-cylinder E, connecting-rods H, nuts Iii,and cranked rock-shaft H, as a consequence of which the 'position ofsuch cylinder vertically can be determined, and it be allowed to riseabove such determined point in case it meets with any obstruction whichmakes such movement neces Sary. i

3. The combination of the platform K and ilap K with thevertically-adjustable rake-cylinder E, substantially as and for thepurpose set forth.

In testimony whereof I have signed my name to this specication in thepresence of two subscribing witnesses.

CLARK M. TERRELL.
